Please check the individual chair models on my site for the vertex and poly count .. The no of samples for the signature rendered image is 2000. Rest are pretty decent but I'm not sure.
I have included only the blend files. You can easily convert them to the format of your choice by using blender to convert the files according to your needs.
Soon I will attach the converted versions as well of what I think are the best settings for the exported files.
The vertex and poly count are high but you can easily decrease the no of polygons by decreasing the levels of subdivision surface modifier which is applied to all the objects. Note that only the chair with a wooden surface attached is rigged and animated.
Also note that the you will be able to render images like the main signature image when you open the plasticchairs.blend file and you will be able to render as the individual images are shown on the right by opening the individual files
Also note that the all files will have to be in the same directory for it to work properly.
Individual price for the 7 models = $ 10 x 4 + $11 + $ 8 x 2 = $ 67
You get it for a price of $ 18 . Savings of $ 49 . Plus any additional discounts which can change over time.
You can also check my profile for other kinds of 3d models such as plastic stools, leather couches, sports balls and more.
